Comment 1 for bug 1187366

I overlooked the first error (below) though. Between callbacks to replay_cb and eval_cb I get a missing cell problem. Probably fixable through attaching the mesh somewhere, I'll let you know.

/// Replay#0 at 0 of up0:0:1:Forward, ||up0:0:1:Forward|| = 8.28722
Unable to extract common cell; missing cell definition in form or expression.
